Hello! My name is Evgeny. Our company «Uralgrit» is the leading Russian manufacturer of abrasive grit. We have a plan, to buy granulated cooper slag (grit) or nickel slag (grit) from any factory or plant in Brazil, for future production of slag blasting media/slag for surface blast-cleaning. But i dont know your native language, so it is very difficult to get any information about it.If you have any, please let me know about it. Waiting for your answer.
